Wash. Rev. Code § 48.44.299
The legislature finds and declares that there is a paramount concern that the right of the people to obtain access to health care in all its facets is being impaired by prepaid agreements which provide benefits, reimbursement, or indemnity by health care service contractors, whether for profit or for nonprofit, which do not provide parity of reimbursement among licensed health care providers performing the same health care services. It is further the intent of the legislature not to mandate the providing of any health care benefit, but rather to require parity of reimbursement for the same health care services performed by all licensees who perform such services within the scope of their respective licenses thereby assuring the people of the state access to health care services of their choice.
